JOHN MELLIN GER, OF GREEN SBU RG, 'PEIflNSYLVANIA.

Letters Patent No. 108,279, dated October 11, 1870.

To all whom it may concern:

Be it known that I, J can Mancunian, of Greensburg, in the county of Westmoreland and State of Pennsylvania, have :invented certain new and useful a full, clear, and exact description. My invention relates to a barrow, of the class which is suspended from a carriage .when at work, and sup ported by it clear of the ground when being moved from place to place.

My improvements consist- Eirst, in the construction and arrangement, as hereinafter setforth, of a carriage mounted on two wheels, a harrow formed of two symmetrical parts or wings, hinged together, and composed each of a ion.- gitudinal piece, from which side pieces dircrge and extend beyond the wheels of the carriage, from which the barrow is suspended, both betbre and behind .them, and having braces extending between the side pieces inside the wheels, and lifting-levers connected with the barren by flexible connections.

Second, in the construction and arrangement, as hereinafter set forth, of the barrow, the carriage, the lifting-levers, and the adjustable or sliding seat for the driver, whereby thecarriage may be properly balanced by the driver, both when working and when the barrow is raised from the gronm In the accompanying drawing- Figure 1 isa plan or top view of my barrow;

Figure 2, a side elevation; and

Figure 3 a near elevation of. the same.

A skeleton frame, A, is mounted'upon a cranked axle, Ii, supported upon wheels G O.

A tongue, D, projects centrally from the frame, to which it is rigidly. attached, and is provided with double and singletrees, for the attachment of the team. A drivels seat, E, is secured to springs e, the ends of which are bent and'fit around guide-rails "F, secured to the frame, and spanning'the axle.

p The seat may be moved either backward or forward upon the rails, as desired, to balance the Innchine upon the wheels. ,I

,The barrow is composed of two parts, correspondingly constructed, and hinged together beneath the carriage inline with the tongue.

Each wing is formedofa stout longitudinal piece,- G,

from the front end of each of which projects a curved side piece, each extending out beyond the wheel,

on its side of the machine, and reaching back about far enough tobring its rear end in line with the axle.-

.A brace, It, extends from each piece G to the middle of each of the curved pieces H, to give them strength, and, at the same time, admit of more teeth being employed, each brace in this instance carrying two teeth. I

From the rear'end of each piece G projects a rear side piece, I, inclining backward, and in' advance of to a rod, 1, which passes ing-levers,

un each wing at brace-bar, K, connects the rear side pieces I J aud the front brace It.

By tbisconstruct-ion, I produce a strong flame,

. which-projects beyond the wheels in front and rear, Improvements in Harrow's, of which the following is but, at the same time, does not inclose them, there being no connection between the rear and front side pieces, outside of the wheels, which maybe taken off the axles without obstruction from the harrowframe.

- The wings are suspended from the carriage "by diag ch'ains L L L L, the two former being, inthis instance, attached to. the piecesG G, and the'latter through eye-bolts on the pieces G G, to form the hinge which unites the wings. V

Upon each front corner of the frame A is secured a bracket-standard, M, to each end of which is pivoted a'lever, N.

Two pulleys, O 0, are secured, in suitable bearlugs, one near each rear similar pulley, o, is mounted oneach side of the frame, in front of the axle.

Chains or cords ,P are se'cnrcd' to the han'ow-i' wings, one to each wing in front of the axle, and nearly beneath the front pulleys, and one to each wing inrear of the axle, and nearly beneath thejrear pulleys. e

The chains pass over the pulleys O .0 o o, and are, attached together to the lower parts of their respective levers N N.

The driver from the-seat can raise eitheror both wings by means of the levers .to the position shown in dotted lines in figs. 2 and 3 of the drawings, and, when so elei'ated, -'the wings are retained in that position by means of I spring-hooked rods ior catches Q Q, which hold the levers until released by the driver. When the wings are aaised for the'transportation of the machine, the driver moves his seat forward to keep the machine balanced, as the rear portion of the harrow is of greatest weight, and extends furthest from the center of the axle.

What I claim isa 1. The construction. and relative arrangement, as

described, of the carriage, the hinged, symmetrical,-

sectional harro w-fmme, suspended and braced between the wheels, but projecting beyond them, both in front and rear, the flexible'connections, and the lifting-levers.

2. The construction and arrangement of the carriage, the hinged, sectional barrow-flame, the liftforth.-

In testimony whereof, I have hereunto subscribed my name.
